SPECIFICATION forming part of Letters Patent No. 522,331, dated July 3,1894.

Application led May 4, 1891. Serial N1k 391,472. `(No modelo To all whomit may concern:

Be it known that I, GEORGE S. STRoNe,-of the'city and county of NewYork, State of New York, have invented a certain new and usefulRegenerative-Boiler Setting, of which the following is a true and exact`description, reference being had to the accompanying drawings, whichform a part of this specification. p

My invention relates to a regenerative boiler-setting or furnaceespecially designed for burning waste products, asl garbage, duc., forwhich purpose a high temperature of the furnace is essential.

My invention will be best understood as de scribed inconnection with thedrawingsin which it is illustrated and in which- Figure 1 is a centrallongitudinal sectionV taken on the line .fr :c of Fig. 2; and Fig. 2 across-section on an enlarged scale taken on the line 'y y of Fig..1.

A is an air tunnel into which air is forced by a blower; from the tunnelA iron air boxes BB, che.,y lead through a smoke passage into a iue Dwhich flue extends up one side over the top and down the other side of alarge arched hre-brick chamber G which is the furnace chamber oftheboiler-setting. The passage D leads into the lower part or ash-pit ofthe chamber G at E and near the bottomV of the chamber grate-bars Fextend across forin-V ing a platform upon which the fuel or refusematter is supported; -this refuse matter is introduced into the chamberG throughv passages H formed through the top of the arch and is piled upon the grate platform F in a pyramid as indicated in the drawings. Fuelmay also be introduced through side openings H though I provide suchopenings principally for the introduction of lfire-irons when desirableand not for the introduction of fuel.

I is a take-off passageleadingfrom the charnber Gas shown and passingthrough the smoke passage O. v

J is the boiler which is provided with a corrugated combustion chamber Kcommunicating with the passage I and from a tube sheet from the end ofwhich tubes L lead through the boiler to a smoke box M from which othertubes N lead back throughv the boiler to the smoke passage O, said smokepassage, as al-v ready explained, being traversed by the passage I andthe iron air boxesB B, dac; From the passage O the smoke passes outthrough the outlet passage O into a suitable stack O2.

The large fire-brick chamber G with its arched top is maintained at avery high temperature the fusion of the bricks being prevented bythepassage of air through the in- Vclosing flue O and the heat thusabstracted from the walls and roof of the chamber being returned to thechamber by the air-blast entering it through passage E., The materialfedthrough the openings H takesv naturally the pyramidical form shown'-which is best adapted to receive heat from the walls and top ofthechamber G, this reflected heat greatly aidingthe heated air-blast inmaintaining a high degree of combustion.A Besides the heat which theair-blast derives fromthe walls of the chamber G it is also lheated bypassingthrough the boxes B in the smoke vpassage theburning gases drivenolf from the fuel in'ch'amber G passing through the ilue in thecombustion chamber K of the'boiler and thence through the boilerV fluesto the smoke passage O; and itwill be seen that by the constructionillustrated abundant provision is made for heating the water of theboiler while at the same time the tire chamber G is maintained at thehighest possible temperature.

The construction of the boiler shown in connection with my regenerativeboiler setting is, Il believe, best adapted for the use; but exceptwhere specifically limited in the claims it will be understood that I donot mean to confine myself to theuse of any particular construction orkind of boiler in connection with my boiler-setting,
